The shady trees - Probably the “lote-trees;” see the note at Job 40:21. The same word is used here.
The willow-trees of the brook - Of the “stream,” or “rivulet.” The Hebrew word (נחל nachal) means rather “a wady;” a gorge or gulley, which is swollen with torrents in the winter, but which is frequently dry in summer; see the notes at Job 6:15. Willows grew commonly on the banks of rivers. They could not be cultivated in the desert; Isaiah 15:7.
